I have heard such a saying long before that China has four most famous ancient cities, which are Lijiang in Yunnan, Pingyao in Shanxi, She County in Anhui and Langzhong in Sichuan. The reputation of the first three ancient cities are really too big, so that they cannot be quiet for a moment. However, Langzhong in Northern Sichuan is well-known, but there are not much reports about it.
